DingLi three-layer single-channel pasture rotary drum dryer (Patent No.: ZL200920089749.2), the equipment with large output, high efficiency and energy saving, small footprint, which is particularly suitable for high-moisture materials such as pasture grass drying with clean type hot blast stove. It can rapid drying moisture from 65-75% to 14-18% in one-time. Dry grass completely retained the nutrients of fresh pasture, bright color, smell fragrance, energy saving 30-50% than ordinary dryer, can maximize energy conservation and drying costs.Suitable for drying elephant grass, alfalfa, wheat straw, barley straw, oat straw, rye straw, rice straw, sorghum stalks, corn stalks, potato vines, bean stalk and 45-75% moisture of pasture straw. According to each material characteristics, production scale, quality requirements, application requirements, cost control, automatic level, on-site conditions, investment quota to optimized drying process technology and equipment configuration services.

  The crushed pasture with about 45%-75% moisture are sent into the drum by conveyor to realize downstream drying. Under the effect of inner shoveling plate, materials are took and scattered constantly, and move in spiral forward method. Through the inner, middle and outer three layers, to realize heat exchange between material and hot air medium.
